气炮加载下炸药强爆轰驱动技术的初步实验研究

Primary Experimental Study on Driving Technique of Strong Detonation Using Gas Gun

利用二级轻气炮进行了炸药强爆轰驱动超高速飞片技术的研究,采用多普勒探针系统(Doppler Pins System,简称DPS)对二级飞片的速度历史进行了测量。初步获得了在较高速度(大于5 km/s)一级飞片的作用下、二级飞片的速度增益情况,并基本掌握了强爆轰驱动技术与二级轻气炮发射技术有机结合的实验技术。初步实验结果表明,采用炸药强爆轰驱动技术可使二级飞片获得较高的速度增益。

Using the loading technique of two-stage gas gun and the doppler pin system,the driving technique of strong detonation is studied.The velocity increment of the secondary flyer is obtained when the velocities of the first flyer surpass 5 km/s.The loading technique of two-stage gas gun and the driving technique of strong detonation are combined very well.The primary experimental results show that the velocity increment of the secondary flyer is considerably large if the two techniques are combined together.
